Advertising by Leprosy Mission Canada

I caught the final frames of an ad/infommercial on TV by Leprosy Mission Canada, the Canadian arm of Leprosy Mission International, an NGO specializing in caring for leprosy patients worldwide. I was a little surprised because the ad overtly stated that the drugs to treat leprosy cost $295. This is clearly not the case. The Multi-drug Treatment is provided free worldwide by Novartis and the World Health Organization. The ad also left the viewer with the impression that deformities can be cured once the drug treatment has been completed. This is wrong also. Deformities have to be surgically corrected and will not be healed through drug treatment alone. I know this is not ethical, but is this kind of advertising even legal?
